“…One last example can be represented by structures that are both forward and backwards oriented, which I will refer to here as unfinished lists. This construction, just as the "common" lists described above, is produced out of retraction, in that it involves the multiple usage of a syntactic slot; more precisely, in almost all the cases observed in the KIParla corpus, the retraction is anchored (Auer and Pfänder, 2007), that is, it is formally marked by the repetition of its initial element. At the same time, the construction is also forward-oriented in that the repeated element, typically a determiner or a preposition, syntactically projects a completion that is either remains unfulfilled, or it is filled by paraverbal material.…”
